CORN I-IULLER.

Application filed November 11, 1925.

This invention relates to improvements in corn hulling devices and moreparticularly to a portable corn hnller adapted for manual operation andfor home use in hulling corn for the preparation of corn mea from wnichcorn bread is to be made.

An object of the invention resides in providing small portable cornhuller adapted for manual operation which includes a cylindrical drum:t'ormed in half sections in which is rotatably mounted a drum so thatthe corn to be hulled is ted between the drum and the casing which areeach provided with outer and inner linings respectively having apluralit-y of hulling teeth thereon adapted by the rotation of the drum,to engage and cut the hulls or shells from the grains of corn thereinwhich are discharged through the slotted portion of the lower half ofthecasing.

The invention includes numerous other objects residing in the details ofconstruction and in the arrangement of, the parts for carrying outthecssential features of the invention. which are hereafter moreparticularly pointed out in the detailed description and claim directedto a preferred form of the invention. it being understood however, thatvarious changes in the size, shape and arrangement of the parts may bemade without departing from the spirit or scope of the invention asherein set forth In the drawings forming part of this application Figure1 is an end elevation of the improved corn huller.

Fig. 2 ma vertical longitudinal sectional view therethrough, taken online 2-2 of Fig. 1.

Fig. 3 is a transverse sectional View thru the lower portion of thecasing and drum, showing the slotted portion of the casin Fig. & is anenlarged detail sectional view taken on. line 44 of Fig; 2 showing therelation of the upper portion of the drum and the casing.

1 indicates the lower end member at one end of the machine which has anupper end member 2 pivotally connected thereto at 2' adapted to form acylindrical end member while the opposite end out the machine isprovided with similar but oppositely formed end members 3 and 4respectively.

These end members are formed in the central portion with hearingretaining portions 5 adapted to cooperate "lor removably retaining thebearing sleeves 6 therein which are Serial Ho. 68,259.

held against rotation by the pins '4'. The arcuate edges or each of theend forming sections ior the device are formed with laterally extendingflanges 9 on the inside of which are annular grooves 10 which areadapted to receive casing sections 11 and 12 respectively which term theupper and lower half or the outer casing for the machine.

Suitable screws 13 may be threaded through the flanges 9 and the endportions of the casing sections 11 and 12 for receiving the end for ningmembers and the casing sections in assembled relation.

The lower :asing section 12 is formed with a plurality of rows elongatedslots 12 in the bottom portion, while the portion of this casinginnncdiately at the bottom of the same is provided with an opening 1efor receiving the door section also formed with a plu rality of slots16, so that upon removal of the door through the operation oi the latchmember 17 of any suitable character, the interior oi the casing may becleaned after the grinding oi? one charge of corn and betore the [illingof the casing with another charge.

The upper casing section Ii l is term-ed with a hopper 1; opening intothe interior oi the casing for receiving and feeding charges of corn tobe hulled into the machine. A piece of steel sheet material 19 mountedin the upper half of the casing adjacent to the casing section 11 havingthe edges mounted in the grooves 10 and is formed with a plurality "ofstruck-out breaker points 20 projecting radially inward there from.

This lining sheet 19 which forms the stationary cutter or breaker memberis ilormed at 21 with an opening registering w'th the lower end of theho per 18. The sheet- 19 is secured in position when the section ll andthe sections 2 and e: respectively are secured together through theedges seating in grooves 10 as above described.

A shaft 22 is rotatably mounted in the hearing sleeves 6 and within thecasing mounts the annular disk members suitably keyed thereon and onwhich is mounted a nmin cylinder 2% which is provided with a cylindricalsheet member or breaker member 25 formed with a plurality of outwardlystruck breaker points 26. These breaker points 26 are rotatable with thedrum and in the rota.- tion thereof it will be seen that a cooperationwill take place between these breaker points and those of the stationarymembers indicated by the numeral 20 which will promounted on the stubshaft 29 carried by the sections 30 formed on the end section 1. Thisgear 28 receives an operating handle 31 so that the shaft 22 may besuitably manually rotated by the operation of the handle. The

end sections 1 cl 0 are formed with suitable leg extensions 32 to term asuitable supportfor the machine assembly.

The meeting edges of the end sections 1 and 2 and 3 ands respectivelyare each formed with projections 33 and respectively the projection 34pivotally inountingr the link meml er 35 which ear the locking leversadapted to engage the recesses 31'' in the projections 33 so that thecasing sections and the end members are retained in closed positionduring the operation of the device.

Upon the supplying of a charge of corn to be hulled throughthe hopper l8and the rotation of the drum in the manner as above set forth, thebreaker p ints and 20 will cooperate to out and breal the shell from thegrains of corn which 7 *ill be chipped oii or cut oil in small piecesand in the rotation 39 of the drum will be discharged through the l3 and16 formed in the bottom casingsection 11. and the door section 15, sothat after the hulling operation during which the hulls are beingdischarged through the slots in the bottom portion of the casing may bereceived in a suitable container placed un der the machine, the door 15may be removed,

and the hulls ofcorn taken from the machine in proper condition forgrinding in order to make the corn meal for the purpose of producingcorn bread.

This machine is designed -particularly for use in homes where corn bread18 used instead of wheat bread or white bread, and

provides a meanswhereby the users of this form of bread may convenientlyhull their own corn. 7 v
